I'm sort of indifferent, because it doesn't solve my problem since my vault is full of exotics and unique weapons/Crota weapons. I should be able to keep one of each exotic and raid weapon at least, or what's the point of doing any of this loot stuff in the first place?
What this reminds me of is the momentary "euphoria" people had when they introduced marks for materials, which was a great quality of life patch. But people were only excited about it because they've been deprived for so long that there doesn't seem to be an acknowledgement of some of the bigger problems. Of course Deej has constantly said that they are aware of the vault space request, but I hope that this isn't their solution to that intrinsic problem with the game.
Now this I agree with. Bungie has a dumb design decision, we are complain, then Bungie throws us a common sense bone, and we rejoice and sing their praises. I was operating under the assumption that this change wasn't meant to address vault space, since it doesn't really give us any additional space at all. It just makes it less necessary to need duplicates (though we never NEEDED dupes).
